plantations without inspection by a competent person. The 
European chestnut is so closely related to our native tree that 
the fungus would doubtless attack it with a violence, caus- 
ing great loss and distress where it is cultiva 
Owners of standing chestnut timber ans the affected area 
are advised to cut and use all trees, both old and young, that 
stand within half a mile of diseased trees, unless protected from 
infection through wind-blown spores by dense forest growth or 
some other natural barrier. This may not prevent the spread of 
the disease through the agency of storms, birds and squirrels, 
but it will at least retard its progress. Old weathered chestnut 
trunks that have been dead several years have no power to 
spread the disease, and these may be cut at leisure for the tannic 
acid factory or for firewood. Trees of good size recently killed 
should be turned into lumber as soon as possible; the fungus 
affects only the bark, but other fungi may afterwards impair the 
value of the wood if allowed to stand too long, Discarded 
the spores they contain; but if - are well within the zone of 
infection such precaution is useles 
t is not considered safe at et to put out chestnut planta- 
tions at any point within the known area of distribution of the 
fungus, and those made elsewhere should be started from the seed 
and carefully guarded. W. A. Murri_t.
